How To Know Your Computer Functions


Tips for Buying Used Computer PC

It’s normally said that it is the computer engineer’s system that is always faulty. The reason for this is that the engineer knows how their systems function and therefore expect the computer to perform at its optimum best. You also can easily know all about the functioning of the system with the few tips below.

1.      Mother Board Speed and Processor Speed:

The mother board is configured with a specific speed i.e. the rate at which it receives and transfer information within the chip on the board. The speed of the mother board ranges from different rating like the example below.

1000 Hz           1 MHz

1000 MHz       1 GHz e.t.c.

Depending on this rating, your computer performs so for you to be expecting your computer to perform beyond its given rate is like a waste of time.

Pentium III board are usually the ones configure to use the “MHZ” while the “GHZ” are usually configured for Pentium IV and above and also most laptops are configured to use the “GHz“

So also your C.P.U comes with it’s with own speed rating which varies just like that of the mother board.

NOTE: Before you get a new processor for your system, make sure that the speed is compatible with that of the mother board hence, the processor is not going to function and you will think that it is bad not knowing that it is its compatibility.

All this information can easily be seen by running “dxdiag” in the search window that show when you click the start menu for windows vista and Window 7 but as for Windows XP and below, you can get by running the same command in the “Run” that is seen in after click the start menu. (Image)

2.      The R.A.M Size

The second thing you must know before you expect any performance from the system is the size of the RAM. The RAM sizes varies from bytes to GHz so the bigger the Ram size, the faster you computer should perform. Below is comparison in the RAM size

1000bytes        1Mb

1000 Mb          1 GHz

Also note that the RAM comes with its speed rating in a form different from that of the mother board and processor (i.e. pc 133). The size of the RAM your computer can hold at a time is mainly determined by the cache size of the system which can be know or seen in the CMOS setup. (Image)

There are 5 different types of RAM which can be used with the system but the common ones are the DIMM, SD, and DD RAM respectively.

Note: Before you replace or get a new RAM for you system, make sure you know the type, the cache size, the speed of your processor. The reason for this is that the mother board, the processor and the RAM work hand in hand to ensure smooth functioning of the system and if anyone of them is below par or higher than it should be, the system might not function or it will function at a very annoying rate.

Some information or messages transferred within the  three component of the computer mentioned above are done at different rate which gives birth to a lot of reason why your computer perform the way it does and I am going to give the example of few of them.

        a.      The FAT a.k.a File Allocation Table:

This is usually used the operating system from Windows millennium below. This is a method where the hard disk of your system is divided into different roles and column with a specific heading which enables your system to retrieve information saved on the hard disk with ease. An example is given below.

1 2 3 4 5 6
1 1,1 1,2 1,3 1,4 1,5 1,6
2 2,1 2,2 2,3 2,4 2,5 2,6
3 3,1 3,2 3,3 3,4 3,5 3,6
4 4,1 4,2 4,3 4,4 4,5 4,6
5 5,1 5,2 5,3 5,4 5,5 5,6
6 6,1 6,2 6,3 6,4 6,5 6,6

 

 

 

 

Each box has it own capacity or size of file it can hold. If for example a document named ten.docx is saved in your hard disk under the table named “1, 1”, the computer will create a place where all the files saved will generally be addressed e.g. reference point example is below

Group One Group Two Group Three Group Four Group Five
Ten.docx1, 1

This is where the computer will first contact below it goes directly to retrieve your file whenever you request for it. In most cases, the reason why the system hangs whenever you request it to open a file is simply because; when you save an uncompleted file, ten.docx into “1, 1” (let say 1, 1 can hold up to 10mb file) and the file is about 5mb, then you saved another that is exactly 5mb, the system will put it the remaining 5mb so that that space is completely filled.

The next time you opened the ten.docx file and you add something else to it and it increase the file capacity to about 8mb, the remaining 3mb will be saved to another box now when you request the system to open that file it may hang due to the fact that it is looking for the exact place where the remaining of the file is saved. So for these reason it is good for the system to be well upgraded.

        b.   N.T.F.S  a.k.a New Technology file System:

This is just the advance type of F.A.T used in Windows NT and above.

The RAM, Processor and the Mother board function in the form of “give and take” that is accordingly. The RAM is virtually responsible for the display of information on the monitor screen. Every information displayed on the screen of your monitor is currently in the RAM and that is the why your system cannot function without the RAM is like removing the eyes and hoping to see without it

The processor is like the brain of the system and without the brain working accordingly, the owner must be really mad so your computer can’t function at all without the processor because it is the main control unit of your system and hence, the reason it is necessary to have a higher processor speed.

The mother board can be compared to the veins and arteries in the human body. It is the main transport medium in the system and it is responsible for transferring information from the C.P.U to the RAM so that it can be displayed and also to carry information from the RAM to the Processor hence, the reason they must be compatible with each other because if they are not, the system is going to having a hell lot of problem.

Also note that this three factor (RAM Size, Processor Speed and Mother Board Speed) are the main factor used to determine the price of a system the other factor are just side attraction.
